SpringMVC后台携带数据，实现局部页面跳转

Posted 2023-03-04 Vodka~

1.前台ajax

    $.ajax(
        url:"/GetCommentContent",
        type:"post",
        data: ,
        dataType:"json",
        async: true,
        //将后端传回的数据，用于渲染评论区
        success:function(data)
            console.log(data);
        
    );

2.后端springmvc

@Controller
public class CommentController 

    private ProcessComment processComment = new ProcessComment();

    //获取所有评论
    @RequestMapping(value = "/GetCommentContent",produces="text/html;charset=utf-8",method =RequestMethod.GET ,RequestMethod.POST )
    public String GetCommentInfo(HttpServletRequest request, HttpSession session)
        return processComment.GetComment(request,session);
    


@Service
public class ProcessComment 
    //获取评论,传到相应页面，并跳转
    public String GetComment(HttpServletRequest request, HttpSession session) 
        CustomerCommentInfo customerCommentInfo = new CustomerCommentInfo();   //自定义对象
        ArrayList<CustomerCommentInfo> CList = new ArrayList<>();
        //规范日期格式
        SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");

        CustomerCommentInfo C1 = new CustomerCommentInfo("vodka","2134239898", "这里的汽车还不错，可选择的品种多，还车方便",Timestamp.valueOf(df.format(new Date().getTime())));
         CustomerCommentInfo C2 = new CustomerCommentInfo("Alice","6456344363", "这里的汽车还不错，可选择的品种多，还车方便",Timestamp.valueOf(df.format(new Date().getTime())));
         CustomerCommentInfo C3 = new CustomerCommentInfo("William","fg46343434", "这里的汽车还不错，可选择的品种多，还车方便",Timestamp.valueOf(df.format(new Date().getTime())));
         CustomerCommentInfo C4 = new CustomerCommentInfo("K","uj65543534", "这里的汽车还不错，可选择的品种多，还车方便",Timestamp.valueOf(df.format(new Date().getTime())));
         CList.add(C1);
         CList.add(C2);
         CList.add(C3);
         CList.add(C4);

         //封装数据进session，再实行跳转
        session.setAttribute("CList",CList);
        session.setAttribute("length",CList.size());
       return "redirect:AdminReview.jsp";   //跳转到自定义页面
